You could never buy just a bare block. Audi would only cell you a block with pistons. The PN for that is 034103101N (your 034103021M is the casting only - which you can't buy).
this was that my etka told me, the original it's NLA (bloque motor=engine block)
And my question is if the ADU block has the same number as the AAN/ABY stamped on it
Because a friend of one customer told him that ADU block has different ref. number in the past, but now Audi dealer sell you the same as AAN/ABY...so I need an ADU block ref. number photo to believe him...because I think that in the past an now a days has the same number on the block 034 103 021M
OK thanks
Yes mate, but I need to know the ADU block serial number
You will never get a block "serial number". At best you will get a casting number. As stated, the engine numbers were stamped in to the head, e.g. "ADU 12345".
Audi's records for your RS2 will only have the number stamped on the head. Nothing about the block.
Sounds like you are having a registration issue or you are trying to verify if the engine is really an ADU. Good lluck with that.

Hi mate, 034 103 021M looks like an Audi reference number....yes, maybe you can't buy a bare block, but I think that it's his ref. number so I win the bet with my customers friend. Same block ref. number between ABY/AAN/ADU
I know that the engine number it's stamped on the head near the cam pulley, but the question was about the block ref. number .... A friend of my customer said that was different than AAN/ABY, And I told my customer that has the same

Looked at the block. Yesterday and it's 034 103 021M. Nothing special about it.
old thread but ...
have an 034 103 021M block and don't think it's ADU,
got it in parts with a lot of other pieces, among others an early AAN-head (tuna-can distributor)
It may be AAN but on the block itself it was mounted a thermostat cover w/part# 035 121 121 A, indicates it's a MC block from A10Q
anyway,
most of the 5-pots are 2.2 litres w/stroke of 86.4 so mby any block (bore = 81.0) may be used as replacement for any other ?
i think the dipstick tube will tell you what block you have. other then that all the blocks on turbo cars are the same with some slight differences that dont realy matter
I have a 034 103 021M block and it appears to be good to mount most of my 3B hardware. On the same side of the block as the casting number, you will see the year it was cast. It appears that the later blocks were machined as per ABY/AAN specs for the dipstick tube and in my case the one way valve to the head. I really need to identify which dipstick tube it requires. Any suggestions on dimensions to measure?
As far as I know it's pretty simple: later blocks require AAN or ABY detachable dipstick tube (2 possible OEM options).
Earlier blocks like 3B already have pressed-in tube.

For nicest OEM fit you need ABY dipstick and ABY intake or proper 3B intake manifold modification or some custom bracket fabricated.
See thread on ABY intake.
